Sustainable Living Innovations Announces Installation of First Manufactured Panels at 303 Battery, Key Milestone in Construction of World’s Most Sustainable High-Rise Apartment Building

303 Battery, the world’s first net zero energy high-rise apartment building, will also supply affordable housing for Seattle community

SEATTLE--()--Today Sustainable Living Innovations (SLI) announced that it has begun installing the high-performance building panels that will make up the 15-story building under construction in Seattle’s Belltown neighborhood. SLI broke ground on 303 Battery in June. When complete, 27 of the 112 total apartments will be designated as affordable.

SLI’s patent-protected technology platform is a new way to build, using wall and floor panels that are manufactured with electrical wiring, plumbing, mechanical, fire safety and network systems equipment pre-installed. By designing and manufacturing buildings like cars and airplanes, SLI’s high-rise buildings go up faster and are more energy-efficient than conventional buildings.

“This is an important milestone for sustainability, for our company, our employees, our investors and so many others who have supported us,” said Arlan Collins, CEO of SLI. “The manufacture and installation of panels is the culmination of many hard years of effort.”

303 Battery will be the world’s first multifamily tower to meet the stringent net zero energy requirements set by the International Living Future Institute’s Living Building Challenge program, the same organization that certified Seattle’s Bullitt Center. Features include solar on the building’s roof, exterior walls and balconies in each unit, greywater and waste heat recovery systems, ultra-efficient hydronic heating and cooling systems, regenerative elevator motors, distributed DC power systems, and SLI’s advanced network systems and data management platform to ensure optimal building operations.

With 303 Battery’s sub-basement and foundation complete, the building’s approximately 900 panels that were manufactured in SLI’s Tacoma facility are being assembled on site. Ten primary panel types will be used in the construction of 303 Battery, with panels for walls, floors and ceilings of each room - living room, kitchen, bedroom, bathroom -- and specialized elevator panels.

303 Battery will be complete in summer 2022 and has been pre-sold to Equity Residential (NYSE: EQR). Equity Residential is an S&P 500 company focused on the acquisition, development and management of rental apartment properties located in urban and high-density suburban markets.
